A baffle 7 is arranged between the two transmission rods 621, and the baffle 7 can synchronously act along with the transmission rods 621. The baffle 7 is extended in the same direction as the panel 4, preferably in parallel, and the upper end of the baffle 7 corresponds to the first air inlet 41 and the lower end of the baffle 7 corresponds to the second air inlet 42.
In the initial state, referring to fig. 5, the first smoke barrier 51 closes the first air inlet 41, the second smoke barrier 52 closes the second air inlet 42, and the transmission rod 621 is located at the upper end of the guide rail 62; when the driving mechanism 61 is started, the electric push rod extends out to push the transmission rod 621 connected with the electric push rod out towards the panel 4 (the direction outside the shell 1), and due to the action of the baffle 7, the other transmission rod 621 is synchronously pushed out towards the panel 4, so that the two connecting rods 623 connected with the transmission rods 621 are pushed out towards the direction outside the shell 1, and the connecting rods 623 can push the corresponding smoke baffle to perform turning motion, and refer to fig. 6; referring to fig. 2, until the two smoke baffles are turned over and opened to a desired angle a, the negative pressure generated by the fan system 3 of the range hood is radiated out through the two air inlets, and the transmission rod 621 is located at the lower end of the guide rail 62.

Preferably, L3 is 1.5 to 2 times that of L1, and L1 is L2.
The existing range hood with a smoke baffle structure is assumed to have the length of the smoke baffle plate of L1+ L2+ L3 and the area of S1+ S2+ S3. The flow rate of the existing range hood with a smoke baffle is Q1, according to the conservation principle in the fluid flow,
when the total flow rate is not changed, Q1 is Q2, (S1+ S2+ S3) × VFlat plate＝S1*V1Flat plate+S2*V2Flat plateIf L1 is L2, S1 is S2, and the formula is simplified as: 2S 1VFlat plate+S3*VFlat plate＝2*S1*V1Flat plate，VFlat plateAverage wind speed through the inlet at a smoke barrier, V1Flat plateV2 is the average wind speed at the first wind inlet 41 through the panel 4 of the present inventionFlat plateTo pass the average wind speed at the second wind inlet 42 on the panel 4 of the present invention, it can be derived that V1Flat plate>VFlat plateUnder the same other conditions, the average flow speed of the partition plate 43 in the middle is higher than that of a single smoke baffle plate, and the oil smoke absorption effect is obviously improved.
Referring to fig. 4, since the second smoke barrier 52 is closer to the center of the pot 100, when the oil smoke is just fried, the oil smoke is sucked by the second air inlet 42 under negative pressure (see the arrow on the rear side of the pot 100, i.e. the oil smoke flow path entering the second air inlet 42), at this time, the oil smoke speed on the outer edge of the pot 100 (the edge close to the front side of the user) is faster, and part of the escaped oil smoke rises upwards and is sucked by the first air inlet 41 under negative pressure (see the arrow on the front side of the pot 100, i.e. the oil smoke flow path entering the second air inlet 42) when rising to the vicinity of the first smoke barrier 51.
When the first smoke barrier 51 is completely opened, the distance from the lower end of the first smoke barrier 51 to the wall 200 is D2, the diameter of the pot 100 is D1, D2 is greater than D1, and the negative pressure area of the first air inlet 41 at the first smoke barrier 51 can completely cover the pot 100.
Along with the parallel translation position difference of transfer link 621, baffle 7 between transfer link 621, its and each keep off the clearance between the cigarette board and can change, when two keep off the cigarette board and open completely, the region between the lower extreme of second baffle 52 and the lower extreme of second air intake 42 is A, and the region of second air intake 42 is B, and the region between the lower extreme of baffle 7 and the lower extreme of second air intake 42 is C to satisfy the area size: a > B > C. The area between the lower end of the first smoke baffle 51 and the lower end of the first air inlet 41 is D, the area of the first air inlet 41 is F, the area between the upper end of the baffle 7 and the upper end of the first air inlet 41 is G, and the area size is satisfied: d > F > G. When the flow rate Q is constant, the smaller S, the larger V, and therefore, the speed magnitude: c > B > A, and G > F > D, the velocity of flow of oil smoke from A region to C region is faster and faster, and A, D region plays the function of keeping off the oil smoke deceleration like this, and C, G region plays the function of the quick oil absorption cigarette of speed increase, fine promotion range hood effect.
In addition, because the driving mechanism 61 is only connected with one of the transmission rods 621, the stress of the whole driving device is not good, and the phenomenon that the transmission rod 621 is stuck to the guide rail 622 is likely to occur, so that the power of the driving mechanism 61 can be well transmitted from the transmission rod 621 connected with the driving mechanism 61 to the other transmission rod 621 by arranging the baffle 7, so that the other transmission rod 621 can also easily move on the corresponding guide rail 622, the stress of the driving device can be greatly improved, and the service life of the driving device can be prolonged.
Referring to fig. 5, on the same side (left side or right side), the connecting rod 623 connected to the first smoke baffle 51 and the connecting rod 623 connected to the second smoke baffle 52 are located at a distance L5 from the connecting point of the two smoke baffle supports and the transmission rod 621, at a distance L6 from the connecting point of the two smoke baffle supports and the corresponding hinge base, at a distance L7 from the connecting point of the first smoke baffle support 511 and the corresponding connecting rod 623, at a distance L9 from the connecting point of the first smoke baffle support 511 and the first hinge base 43, and at a distance L10 from the connecting point of the second smoke baffle support 521 and the corresponding connecting rod 623, at a distance L10 from the connecting point of the second smoke baffle support 521 and the second hinge base 44. In order to realize that one set of driving device can open two blocks of smoke at the same angle, L5-L6-L7 and L9-L10 are required to be met. The connecting rod 623 connected with the first smoke baffle 51 and the connecting rod 623 connected with the second smoke baffle 52 have the same length. The sum of the lengths of L1+ L2+ L3 is 70% to 80% of the length L of the entire panel 4.
In the opening state, the distance between the baffle 7 and the partition plate 45 is H, the length ratio of H to the area B is 0.4-0.6 times, and the optimal oil smoke absorption effect state H/B is equal to 0.5 times.
